Wife goes to friends with the 2011,stays about one hour. Goes to start the sorrento, nothing but Click. Trys it a few times, nothing but Click. Gives me a call, car wont start, it Clicks. I figure dead batt., bring jump box. 20 minets later Im at car, take look under hood.Batt connections look good, belt is tight. Give it a try, it starts rigth up, no Click. Only thing I notice is the mileage counter has reset itself. Didnot loose radio presets or anthing else,strange.With car running Ive got 14.7 volts at batt.,12.9 when off. ?????
